Hi @YM-MAA-IT Jayakumar,

A 403 Forbidden error when accessing OneDrive after moving to Microsoft Entra ID usually indicates that the account can authenticate but does not currently have permission to access its OneDrive site.

To help narrow this down, could you check the following?

Confirm that the affected user has an active license that includes OneDrive for Business (SharePoint Online).
Try opening OneDrive from the Microsoft 365 app launcher or by browsing to: https://<yourtenant>-my.sharepoint.com
Verify whether the user’s OneDrive has been provisioned successfully. If the personal site has not yet been created, a 403 error can occur.
Sign out of all Microsoft 365 accounts in the browser, then test again in an InPrivate/ Incognito window using only the affected work account.

You may also find these Microsoft articles helpful:

Could you also clarify:

Does this affect only one user or multiple users?
Does the error occur in both the browser and the OneDrive sync client?
What is the full URL the user is trying to access?
Was the user’s UPN or sign-in address changed during the migration?
Has the user’s OneDrive site been confirmed to exist in the SharePoint admin center?

If everything above has already been verified and the issue began after the migration to Microsoft Entra ID, it may require your Microsoft 365 administrator to review the tenant configuration or open a support request with Microsoft, as those checks are beyond what can be performed through the Community forum.

Hi Maksym,

Your scenario appears to be different from the original poster's issue because you are accessing OneDrive/SharePoint through FileZilla Pro, which is a third-party application.

I could not confirm from Microsoft documentation that a Microsoft-side change approximately one month ago specifically caused FileZilla Pro versions 3.60 or 3.69 to start returning 403 errors. Therefore, I would not want to assume that the error was caused by a recent Microsoft change without further evidence.

As a first check, please try accessing the same OneDrive or SharePoint location directly in a web browser with the same account.

If it also returns 403 in the browser, the issue may be on the Microsoft 365/SharePoint side. Microsoft lists permissions, a locked OneDrive site, and SharePoint Online service issues among possible causes of a 403 error.

If the browser works normally but FileZilla Pro alone returns 403, that would point more specifically to the FileZilla connection, authorization, or compatibility with the Microsoft service.

FileZilla's current documentation indicates that its OneDrive connection uses browser-based authorization, so you may also try removing/re-authorizing the OneDrive connection in FileZilla according to their documentation.

Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.)

If the issue persists, please provide the exact 403 message/log shown by FileZilla after authentication (with any account, tenant, or other personal information removed), and confirm whether the same account can access the OneDrive/SharePoint location successfully in a browser.

Please also note that this is a user-to-user community forum, so I cannot reconfirm internal service changes directly with Microsoft or access Microsoft's backend from here. I can, however, help narrow down the cause based on the documented behavior and the results of the tests above.
